“…4 Majority of the times, separated instrument retrieval procedure leads to weakening of tooth structure which may cause fracture and, thus, loss of the tooth, all this is due to overzealous canal enlargement. 3,4 Many times, instruments are separated apical to the curvature of the canal. In such cases, a safe access to the site of separation may not be achieved.…”

“…4 Easy removal of the separated instrument depends upon the anatomy of the tooth which includes the length, diameter, canal curvature and additionally limited by root morphology which includes the thickness of dentin and the depth of external concavities of root. 4 Majority of the times, separated instrument retrieval procedure leads to weakening of tooth structure which may cause fracture and, thus, loss of the tooth, all this is due to overzealous canal enlargement. 3,4 Many times, instruments are separated apical to the curvature of the canal.…”

“…A long shank tapered fissure carbide bur (169L) was used to make vertical cut towards the furcation area to bisect mesial and distal halves of #36. A fine probe was passed through the cut to ensure separation [4][5][6][7][8] (Figs 3 to 5). …”

Procedural errors like separated instrument have always been a hindrance for successful endodontic therapy. However, it becomes more challenging when there is an added condition of root resorption in the same root in which instrument is separated. Here, we present and discuss such a case where instrument retrieval was unsuccessful and had to restore to surgical techniques like hemisection and extraction of affected root of the tooth followed by prosthetic rehabilitation.

“…The success of root canal treatment depends on the results of the cleaning and shaping process. However, there is a risk of broken files because its presence inhibits the process of cleaning, shaping, and filling, thereby leading to treatment failure [1]. A broken file often occurs in the molar teeth, especially at the lower jaw because of poor access, small diameter, and sharp curvature of the root canal.…”

Broken files affect cleaning, shaping, and filling processes of the root canal, thereby causing maintenance failure. Objective. This report explains how to remove broken files using ultrasonic instruments and endodontic micro forceps. Case Report. A 25-year-old female patient had incomplete root canal treatment at the lower right first molar 1 week ago. There were radiolucency in the bifurcation and apical root and the presence of broken files in the 1/3 coronal mesiolingual root. The retrieval started by making a staging platform with an ET20 ultrasonic tip. Endodontic micro forceps were used including a screw wedge that works by clamping the file fragments through a mechanical lock and pulling them to the coronal. Conclusion. It is possible to successfully remove broken files from the root canal using ultrasonic instruments and endodontic micro forceps.

Among the most common problems within dental professionals, is the fracture of rotary instruments of nickel and titanium root canal files (NiTi), when performing a procedure on a patient. Therefore, the objective of this work is to compare the in vitro resistance to cyclic fatigue of K3XF and TFA rotatory instruments, in continuous rotation and adaptive motion. For this, a static and cyclic fracture test was used and a fracture pattern was searched. The numbers of cycles until the fracture and the length of the fragments were determined. Of all the groups evaluated, K3XF-A exhibited the best resistance to cyclic fatigue. In future research, it will be performed an autoclaving and immersion cycles in sodium hypochlorite to be able to determine the separation causes of the rotary instruments. As a recommendation, the operator could significantly influence the decrease in resistance to cyclic fatigue due to the misuse of rotary instruments. RESUMENEntre los problemas más comunes entre los profesionistas dentales, es la fractura de los instrumentos rotatorios de limas de canales radiculares de níquel y titanio (NiTi), cuando se lleva a cabo el procedimiento al paciente. Es por eso, que el objetivo de este trabajo es el comparar la resistencia in vitro de la fractura cíclica entre los instrumentos rotatorios K3XF y TFA, en rotación continua y movimiento adaptativo. Para esto, se utilizó la prueba de fractura cíclica y estática y el patrón de fractura fue evaluado. El número de ciclos hasta la fractura y la longitud de los fragmentos fue determinado. De todos los grupos evaluados, K3XF-A presentó la mejor resistencia a la fractura cíclica. Como trabajo a futuro, se utilizará ciclos de inmersión en hipoclorito de sodio y autoclaveado, para ser capaces de determinar las causas de separación de los instrumentos rotarios. Como recomendación, el operador puede influenciar significativamente la disminución de la resistencia a la fractura cíclica utilizando de una manera errónea el dispositivo.
